| 摘 要： | 通过野外实地调查对福州地区林龄7年的柑橘果园生态系统碳氮储量及分布特点进行了研究,结果表明:有机碳储量为158.282 t.hm-2,其中土壤(0-100 cm)碳储量为151.734 t.hm-2,占总有机碳储量的95.86%,植被碳储量为6.548 t.hm-2,占4.14%;氮储量为14.602 t.hm-2,其中土壤(0-100 cm)氮储量为14.399 t.hm-2,占总氮储量的98.61%,植被氮储量为0.203 t.hm-2,占1.39%.相关分析表明,柑橘果树不同器官碳氮含量呈极显著负相关(r=0.976),不同土层土壤的碳氮含量呈极显著正相关(r=0.998). |

| Abstract: | Organic carbon and nitrogen storage in 7 years old citrus orchard was detected with the field investigation and measurement.The results showed that carbon storage in the ecosystem was 158.282 t·hm-2,in which soil(0-100 cm) carbon storage was 151.734 t·hm-2,vegetation carbon storage was of 6.548 t·hm-2,accounting for 95.86% and 4.14% of total carbon storage,respectively.Nitrogen storage in the ecosystem was 14.602 t·hm-2,in which soil(0-100 cm) nitrogen storage was 14.399 t·hm-2,vegetation nitrogen storage was 0.203 t·hm-2,accounting for 98.61% and 0.203% of total nitrogen storage,respectively.According to the correlation analysis,carbon and nitrogen contents in different organs were significantly negatively correlated(r=0.976),and soil organic carbon and nitrogen contents in different soil layers were significantly positively correlated(r=0.998). |
